Mathematics 8 Illustrating Triangle Congruence.ppt
- 1. MATHEMATICS 8 Maria Theresa A. Celebre Teacher I Illustrating Triangle Congruence (M8GE-IIID-1) 8th GRADE
- 2. Here’s what you will learn for today: ● Discuss the idea of congruence. ● Illustrate triangle congruence. OBJECTIVES:
- 3. LET’S PLAY A GAME! BRING ME THE FOLLOWING OBJECTS: ● PAIR OF EARRINGS ● PAIR OF SHOES ● EYE GLASSES ● PAIR OF NOTEBOOKS
- 4. TO WHOM SHOULD I PAIR At a count of five, find your partner holding the same shape of triangle as yours and shout “BASIC LANG”! if you are done. Just stay with your partner for some questions/instructions.
- 5. Name your triangles. TO WHOM SHOULD I PAIR
- 6. What kind of triangles are they? TO WHOM SHOULD I PAIR
- 7. Which parts of one triangle corresponds to the other? TO WHOM SHOULD I PAIR
- 8. What is the symbol for correspondence? TO WHOM SHOULD I PAIR
- 9. Why did you say that they are congruent? TO WHOM SHOULD I PAIR
- 10. What is the symbol for congruence? TO WHOM SHOULD I PAIR
- 11. LET’S PROCESS! Answer the following questions: What are congruent triangles? What is the symbol for congruence? How many congruent corresponding parts are there? What is the symbol for correspondence? How do you put identical markings on congruent corresponding parts. Illustrate. Where can you see/find congruent triangles?
- 13. LET’S DO IT!
- 14. 1. △ABD ≅ △ CBD. Write down the six pairs of congruent corresponding parts.
- 15. 2. Draw △MAX ≅ △ KFC where, MA ≅ KF AX ≅ FC MX ≅ KC ∠ M ≅ ∠ K ∠ A ≅ ∠ F ∠ X ≅ ∠ C
- 16. 3. Which of the following shows the correct congruence statement for the figure on the right. A. △ PQR ≅ △ KJL B. △ PQR ≅ △ LJK C. △ PQR ≅ △ LKJ D. △ PQR ≅ △ JLK
- 18. YOU GOT THIS! Illustrate the triangle congruence by listing down and putting identical markings on the congruent corresponding parts.
- 19. 1. Write the six congruent corresponding parts. Refer to the figure on the right.
- 20. 2. Draw the figure and mark the identical congruent corresponding parts of △ RUB ≅ △ TUG
- 21. TAKE NOTE!
- 22. Draw two congruent triangles and identify their congruent corresponding parts.
- 23. “The best angle from which to approach any problem is the TRY-ANGLE.”
